ばね部の位置的な因果関係は特に見られない。(Prior art) In a conventional electronic watch, a conduction spring that supplies power to a circuit board is a part of a battery holder, and the battery holder itself is connected to other parts by an engaging part that is a part of the battery holder. Some have a battery holder with a conductive spring attached to the component. However, there is no particular positional causal relationship between the engaging portion and the conductive spring portion.

てしまい、現在時刻が狂つてしまう。(Problems to be Solved by the Invention) FIG. 4 shows the state in which an electronic watch using a conventional battery holder with a conductive spring is dropped. In the state before falling, the conductive spring portion 5 is in contact with the circuit board 4 and conductive is established. b is the state at the time of the fall. Due to the impact of the fall, a force acts on the battery 1 that tends to separate it from the circuit board 4. This force is transmitted to the battery holder, and the conduction spring portion 5 is also separated from the circuit board 4, and the conduction with the pattern is interrupted. When the battery returns to its normal position and continuity is restored, the IC function will set the time to 12:00 and the current time will be incorrect.

However, the engaging parts, which are the ends and the base of the conductive spring, are hung on the circuit board, and the conductive spring part hits the side opposite to the hanging surface of the board. I tried to insert it.

In FIG. The battery part 2-1 of the battery holder 2 presses the top surface of the battery 1 and restricts it to a predetermined position to establish conduction with the battery anode part. Reference numeral 3 denotes an engaging portion of the battery holder 2, which is shaped like a window. A portion of the engaging portion 3 enters the underside of the overhanging portion 4-2 of the circuit board 4 and is firmly attached thereto. There is a conductive spring part 5 inside the engaging part 3,
Power supply pattern 4 on the overhanging portion 4-2 of the circuit board 4
-1 and has continuity. Since the engaging portion 3 supports the lower side of the circuit board 4, the conductive spring portion 5 maintains its spring properties and conduction is ensured. Now, when this electronic timepiece receives a strong shock due to being dropped, etc., a force is generated that tends to move the battery 1 upward. This force is also transmitted to the battery holder 2. Similarly, it is transmitted to the root portion of the conductive spring portion 5, but due to the grip of the engaging portion 3, it does not separate from the power supply pattern.
